QNEET-2021-Ph-654: NEET 2021 Physics - Class 11 NEET-2021-Ph-654 Solution: A body is executing simple harmonic motion with frequency 'n'…
A body is executing simple harmonic motion with frequency 'n' the frequency of its potential energy is: 4n n 2n 3n
Multiple Choice Options
- A 4n
- B n
- C 2n
- D 3n
Step-by-Step Verified Solution
Displacement equation of SHM of frequency 'n'
x = A sin ( _ t) = A sin (2 � nt)
Now,
Potential energy
U = 1 2 k x 2 = 1 2 K A 2 sin 2 ( 2 � n t )
= 1 2 k A 2 [ 1 _ cos _ ( 2 � ( 2 n ) t ) 2 ]
So frequency of potential energy = 2n
